Activated Carbon (Powder) - China

Brief Overview

Activated carbon, also known as activated charcoal or activated coal, is a form of carbon with small and low-volume pores which increases the surface area available to facilitate adsorption or chemical reactions. The increased surface area of activated carbon makes the material suitable for adsorption, a phenomenon where particles such as atoms, ions or molecules of gas, liquid or solid are adhered to a surface. These particles are held within the carbon’s internal pore structure by electrostatic attraction or chemisorption. This adsorption ability allows activated carbon to play an important role in many industries as it can help to reduce dangerous matter in chemical process, activate chemical reactions, and also act as a carrier for biomass and chemicals.

The most common product forms of activated carbon include:

• Extruded 

• Granular 

• Powder

The different forms of activated carbon allow it to be used in a wide range of applications according to their preferred properties.

Manufacturing Process

Activated carbon is usually made from coconut shell charcoal or coal. To make activated carbon, it can be done by burning activated carbon material in a tightly closed place, so that only the pyrolysis process occurs.

Processing the material into activated carbon is in principle by opening the pores of the carbon charcoal which initially has an area of 2 m2/g to 300-2000 m2/g so it is called activated charcoal. There are 2 ways to activate charcoal into activated carbon, namely by using a weak oxidation reaction using water vapor at a temperature of 900-1000°C or by dehydration using chemicals or salts.

Applications

1. Water & Wastewater Treatment

Powdered activated carbon (PAC) is widely used in water treatment plants and industrial effluent systems to remove chlorine, organic compounds, taste & odour, algae and macromolecules. yrdcarbon.en.made-in-china.com+2naturecarbon.com+2
2. Food & Beverage / Sugar & Oil Refining / Pharmaceutical

Because of its ultra-fine particle size and high surface area, PAC is particularly suited to decolourisation, deodorisation and purification of liquids in the food & beverage, sugar, edible oil and pharmaceutical sectors. huameicarbon.com+1
3. Chemical Manufacturing & Solvent Recovery

PAC from China is also used as a carrier or adsorbent in chemical processes: removing phenols, heavy metals, chlorinated organics, recovering solvents, and treating industrial wastewater streams. yuanlicarbonyl.com+1
4. Air & Gas Purification

The fine powder form of activated carbon enables fast adsorption of volatile organic compounds (VOCs), odours and gases in air and gas purification systems. effluenttreatmentchemicals.com+1
